[Intel-gfx] ✗ Fi.CI.BAT: failure for drm/i915: Check HAS_PCH_NOP when install or reset dispaly IRQ

[Wang, Elaine]

Reply to correct thread.

The failed case is KBL hang. This patch shouldn't impact platforms that have non-zero num_pipes.
So the KBL hang isn't a regression caused by this patch. According to below kernel log before hang
(https://intel-gfx-ci.01.org/CI/Patchwork_3266/fi-kbl-7500u/dmesg-during.log),
It should be the same issue as Bug 98670 - [BAT] WARN_ON(dev_priv->gt.awake) during 
drv_module_reload_basic (https://bugs.freedesktop.org/show_bug.cgi?id=98670),
